fvdl e5bc90f40c Merge with Lite2 + local changes 1998-03-01 02:20:01 +00:00
mrg d90485202c - add defopt's for UVM, UVMHIST and PMAP_NEW. 
- remove unnecessary UVMHIST_DECL's.
 1998-02-10 14:08:44 +00:00
mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

kleink 5d7a8f4a16 Modify the recent sigaltstack() interface change to use the __RENAME() scheme; 
add __sigaltstack14().
 1997-11-29 18:38:20 +00:00
mycroft d0a1101d26 Disable an effectively no-op reference to u_kproc, with an explanation of what 
should be done with it eventually.
 1997-10-16 02:45:39 +00:00
mycroft 701f15db33 Reinstate P_FSTRACE, with different semantics: 
* Never send a SIGCHLD to the parent if P_FSTRACE is set.
* Do not permit mixing ptrace(2) and procfs; only permit using the one that
  was attached.
 1997-04-28 04:49:27 +00:00
mycroft 43a0dc8b74 Remove remnants of P_FSTRACE, which is no longer used. 1997-04-28 02:51:41 +00:00
mycroft ead5e1a6f7 When stopping a process being traced through procfs, wake up the *parent* (in 
case it happens to be doing a WAIT.
 1997-04-28 02:36:05 +00:00
mycroft 1cf91041df Nuke the old COMPAT_09 truncation of UIDs, GIDs, process and process group IDs. 1997-04-23 18:59:53 +00:00
kleink c9c13ef470 Changed killpg1() to 'succeed' even if a process group consists of 
SZOMB processes only; the POSIX.1 definition of a background process
group implies that kill(2)ing such a process group must succeed.
 1997-04-03 21:08:27 +00:00
mikel 4ab6dc7d2e allow examination of SIGKILL and SIGSTOP signal handlers (but still 
disallow changes); from Klaus Klein in PR standards/3398.
 1997-03-27 07:52:25 +00:00
cgd e7af2a8237 * catch up with system call argument type fixups/const poisoning. 
* Fix arguments to various copyin()/copyout() invocations, to avoid
  gratuitous casts.
* Some KNF formatting fixes
 1996-12-22 10:21:06 +00:00
cgd 8595fc3073 make coredump() use more sensible error returns (even though they're 
not used by anything, for now), and implement MNT_NOCOREDUMP by checking
whether or not MNT_NOCOREDUMP is set on the file system where the dump
would land (i.e. the file system of the process's current working
directory), and disallowing the core dump if it's set.
 1996-10-23 23:13:19 +00:00
mrg 8fd70c1fe1 in coredump(), check the SUGID bit rather than testing various parts 
of the cred structures.  this prevents a previously set[gu]id process
from generating a core file.
 1996-10-18 08:39:34 +00:00

traditional usage.
 1996-01-04 22:21:33 +00:00

prototypes into scope.

Rename ss_flags bits.
 1995-08-13 22:53:59 +00:00
mycroft 73d0d3717e Don't toss out tty stop signals if we're being traced. 1995-07-24 03:18:42 +00:00
christos 1a5a3c9199 Extracted all of the compat_xxx routines, and created a library [libcompat] 
for them. There are a few #ifdef COMPAT_XX remaining, but they are not easy
or worth eliminating (yet).
 1995-06-24 20:33:55 +00:00
mycroft d7e904a697 Fix various signal handling bugs: 
* If we got a stopping signal while already stopped with the same signal,
the second signal would sometimes (but not always) be ignored.
* Signals delivered by the debugger always pretended to be stopping
signals.
* PT_ATTACH still didn't quite work right.
 1995-06-08 23:51:01 +00:00
christos 3d1b06ab09 - new copyargs routine. 
- use emul_xxx

- deprecate ep_setup
- call sendsig and setregs indirectly.
